smart power plug with ESP8266 settings

[Blisk]

I have smart power plug with ESP8266, problem is because it shows only Power and Energy. If I setup HLWLB CF1 I also get Volttage and Current but it shows all 0 which is wrong. Withouth that I get right power but only that. What I setup worng here?

May depend on which specific plug you have. Your "Based on" in the template suggests some BlitzWolf energy monitoring plug, but they have several different models, not all with same gpios. You may have a wrong template configured.

You can search for template strings in https://templates.blakadder.com/

If you configure Module 45 without setting different gpios in a template, you get:

gpio   num ty comp        
GPIO0  0   D3 Led_i1      320
GPIO2  2   D4 LedLink_i   576
GPIO5  5   D1 BL0937 CF   2720
GPIO12 12  D6 HLWBL SEL_i 2624
GPIO13 13  D7 Button1     32
GPIO14 14  D5 HLWBL CF1   2656
GPIO15 15  D8 Relay1      224

I have a plug working with that config, but yours may be different again.

I have this smart plug on picture all works ok but can't get Voltage and current, thats why I am asking.
This what you give me doesn't work on my plug.

Such an image is zero info about what specific brand, model and revision it is, as the plastic case can be common across different devices.

I didn't want to give a link so, someone can accuse me of propagating something. I buy this wifi smart power plug and in it was ESP8266

I have uploaded 5 of them with Tasmota all works ok only no Voltage and no Current.

Matching some generic no-name Tuya plug (TNCE looks like the seller, and not about the hardware model) and a template for a Blitzwolf device is not a workable plan. Those devices can have quite different pin connections on the inside, and just guessing takes a lot of tries to get energy monitoring pins correct.

However, since you do have numbers for consumption, at least some of what you have seems right.
I've extracted a table from the templates repository counting what pins are used for the BL0937-related gpios across many ESP8266 devices:

.......  BL0937 CF  HLWBL CF1  HLWBL SEL  HLWBL SEL_i
Gpio.00                                             2
Gpio.01                                             3
Gpio.02                                             2
Gpio.03                                1           33
Gpio.04        134         18                       1
Gpio.05        108        181          3            4
Gpio.12          4          8         14          224
Gpio.13          6          4          2            4
Gpio.14          3        104          1            4
Gpio.15                                5            3
Gpio.16                                1            6
.......  BL0937 CF  HLWBL CF1  HLWBL SEL  HLWBL SEL_i

As you can see, gpio 5 and 12 are commonly used, but gpio 12 is usually inverted HLWBL SEL_i instead of HLWBL SEL

Thank you for your answer, I just find another smart power plug which have already set pins as on picture I bought it as tasmota on aliexpress and now I can see voltage and Current. Funny is because I can set voltege, power and current but when I check tasmota website it shows 150mA more current than what I set Backlog VoltageSet 234.5; CurrentSet 0.452; PowerSet 106.
whatever I set for current it doesn't go lower than this on picture . Power and Voltage are correct

Did you copy calibration commands from some other device? It is to be done for each individual device.

I use multimeter and meassure voltage and current on 100W regular bulb, that command works but it is funny 6 the same devices some are ok some all other is ok just current wont go lower than 595mA
